Abstract

1,157,009. Leak detectors. LEYBOLDHERAEUS-VER WALTUNG G.m.b.H. Sept.30, 1966 [Oct. 2, 1965], No.43909/66. Heading G1S. In apparatus for detecting leaks, in which a test gas is contained in the apparatus 1 a probe 6 is connected to a gas detecting device 2 through a pipe consisting of one section 3 formed as a rigid metallic pipe connected to a terminal section of flexible pipe of smaller cross-section than the internal cross-section of the metallic pipe.
